N,N’-Bis(5-isophthaloyl)naphthalene diimide (CAS 350024-36-1) has a molecular formula of C??H??N?O? and a molecular weight of 572.50 g/mol, featuring isophthaloyl groups attached to the imide nitrogen atoms of the naphthalene diimide core. As a ??-conjugated aromatic diimide, it is widely used in synthesizing organic semiconductors and metal-organic frameworks (MOFs) for its excellent charge-transport and self-assembly properties. It requires sealed storage under cool, dry, dark conditions to prevent hydrolysis or oxidation, maintaining structural integrity for optoelectronic and material science applications.
